The link won't function for me, but I'm thinking there's no need for the Chinese to weaponize a virus, their hideous, disgusting culinary practices are enough. Obviously, after they slaughter a bat, a cat or a dog, they don't even think to wash their hands before they prepare the creature to be devoured. Leaving it hanging out in the open without refrigeration sure gives the germs/virus the poor animal carried while alive, a perfect opportunity to multiply in what is probably only partly-cooked meat.
It's enough to put me off Chinese food for life.
